GripCap - The Fidget Spinner Bearing Cap

I recently printed my first spinners and didn't like any of the bearing caps, except for the cap that's included in thing:1871997, as it has a nice indentation that keeps your finger tip centered. Unfortunately it could only be used on one side, because of the peg that protrudes from the other side.

The Grip Cap is based on the same general design, so it has the same nice grip and works with 608 bearings, but can be used for both sides of the bearing and has smoothed edges.
